Subject: Update settings.py
X-Git-Tag: v1.10.0-beta.rc1~1^2~35

Update settings.py

Django gives a system error on MariaDB on VARCHARs longer than 255 chars. This was a limitation in older versions of mysql.
Meaning: You cannot run Paperless-NGX on older version were this limitation were present, meaning Django plays it extremely safe by giving an error.
This fixes this problem.
